Sea quark-gluon effect on the magnetic octupole deformation of decuplet baryons

Preeti Bhall, Ritu Garg, Alka Upadhyay

The magnetic octupole moment of $J^{P} = \frac{3}{2}^{+}$ decuplet baryons are discussed in the statistical framework, treating baryons as an ensembles of quark-gluon Fock states. The p…

Sea-quark dynamics in decuplet ( $\frac{3}{2}^{+}$ ) $\to$ octet ( $\frac{1}{2}^{+}$ ) transition quadrupole moment

Preeti Bhall, Alka Upadhyay

We investigated the electromagnetic quadrupole transition of baryon decuplet ( $J^{P} = \frac{3}{2}^{+}$ ) to octet ( $J^{P} = \frac{1}{2}^{+}$ ) using the statistical framework together with th…

Open charm mesons in variational scheme and HQET

K. K. Vishwakarma, Ritu Garg, Alka Upadhyay

The charm ( $D$ ) and charm-strange ( $D_{s}$ ) mesons are investigated in a variational scheme using Gaussian trial wave functions. The Hamiltonian contains Song and Lin potential with…

Importance of strange sea to the charge radii and quadrupole moment of $J^{P} = \frac{1}{2}^{+}, \frac{3}{2}^{+}$ baryons

Preeti Bhall, A. Upadhyay

A statistical framework in conjugation with the principle of detailed balance is employed to examine the low-energy properties i.e. charge radii and quadrupole moment of J $^{P}$ =$\fr…

Analysis of 2S singly heavy baryons in HQET

K. K. Vishwakarma, A. Upadhyay

We have employed HQET to determine the masses of radially excited ( $n = 2$ ) S-wave charm and bottom baryons. The HQET Lagrangian containing the non-perturbative parameters is shown w…
